Alpha Identification Based Otp System

In the realm of contemporary digital security, this study focuses on enhancing Secure OTP Management. The Alphabetical ID system is a pivotal solution to bolster security and streamline user authentication. It strategically displays three alphabetic characters in both the generated OTP sent to the user and the interface for OTP input. This design empowers users to identify the latest OTP among received codes, addressing the dilemma of consecutive OTPs causing confusion and potential access denial. The Alphabetical ID system revolutionizes identification protocols, significantly reducing the likelihood of unauthorized access. This heightened identification capability serves as a robust safeguard for sensitive data and reinforces the integrity of digital transactions. The synergy between the Alphabetical ID system and the conventional OTP process marks a paradigm shifts in user authentication, achieving an optimal balance between user experience and identification precision. As businesses transition towards digitization and online interactions, the Alphabetical ID system emerges as a pioneering leap, offering a reliable shield against unauthorized access and catalyzing fortified digital security. This inventive solution stands as a pragmatic answer to the challenge of identification in OTP management, culminating in an elegant fusion of simplicity and efficacy. The proposed Alphabetical ID system is poised to redefine the landscape of Secure OTP Management by placing a heightened emphasis on user-friendly identification mechanisms within the broader context of digital security.

Secret Communication Using Multi-Image Steganography with Face Recognition and OTP System

Abstract: Our Proposed system is to develop a Web operation for hiding information in any image train to ensure the safety of the exchange of data between different military parties and give better security during communication transmission. We use the LSB fashion. The proposed approach uses a steganography algorithm to bed data in the image lines for military operations. For security purposes, we used modules face Recognition fashion with the AES algorithm for Strong Security purposes. And we use the cover channel fashion as an information-hiding fashion that can be exploited by a process to transfer information in a manner that violates the system security programs. Image steganography is the main aspect of information caching where the ciphertext is bedded into an image called a cover image which is coming to insolvable for the interferers to see with their naked eyes. The retired information can be any textbook, images, audio, or indeed videos inside a cover image. The abstract description ofMulti-image Steganography is that the secret law is divided into multiple corridors and is etched into multiple cover images. So we proposed two image steganography ideas to make it veritably grueling for the hackers to conceal the data. This paper proposes the Least significant bit( LSB) fashion of Steganography and the Advanced Encryption Standard( AES) fashion of Cryptography to make a safe and secure system. Then the sender and the receiver use the same key to encrypt and decipher the data which is popularly nominated a symmetric crucial Keywords AES Algorithm, LSB Algorithm, and Steganography.

Electronic Voting System with Blockchain

Electronic voting or E-voting, is the process by which votes can be cast through electronic means, such as an Electronic Voting Machine or voter’s personal device. This study aims to create a reasonably secure and hassle-free system through which votes can be cast by users through their phones with relative ease as compared to traditional means. Voting takes place through an app on the device, in which the user signs in with their ID and PIN. This lets the user establish secure means of communication with the server by exchanging encryption keys and authorization tokens, which in turn lets the user and server authenticate secure using various factors of authentication, such as a Time-based OTP system, to verify the user’s identity and let the cast their vote securely onto the server’s private blockchain. On the server side there will be “nodes” and an “owner” server that share a private blockchain, which handle counting the votes, authentication, user creation and managing the voting system and its configuration. After all the authentication is done, the user can cast their vote in the final part of the process. This will be verified using a token generated separately on both client and server side. If it matches then the user will get an appropriate message confirming their vote being cast, and upon failure the user can contact the appropriate authority conducting the poll for further action.

Social Media Security based on OTP and Biometric System

One-time passwords are a method for validating yourself to a framework using a solitary utilize mystery that is particular to you and may have a restricted day and age of legitimacy. At the end of the day, you have two passwords. One that you know. One that is produced for you or sent to you. You ne

NFC와 OPT를 활용한 아두이노 다중 인증 시스템

기존의 NFC 인증 시스템의 문제점은 고정된 킷값 사용 시 발생하는 보안적인 문제들과 NFC 인증 시스템에 별도의 NFC 태그를 사용해야 하는 불편함이었다. 본 논문에서는 이러한 문제점을 해결하기 위해 기존의 킷값을 발생하는 알고리즘에 OTP를 병행하여 처리하도록 하여 보안성을 높였고, 통합된 안드로이드 어플리케이션을 개발하여 사용자의 편의성을 높였다. 또한 이러한 인증 기술을 아두이노에 적용하여 향후 사물인터넷(IoT) 환경의 보안 기술과 인증 시스템 기술의 활용 방향을 제시하였다. The issued problem in the existed NFC authentication system is the security problem caused by the fixed key and the inconvenience occurred by the extra NFC tag. This paper aims to enhance the security level through OTP system added up the key generation mechanism and the convenience level by the integrated Android App. This proposed authentication system on Arduino will be widely applied to IoT security and will be used on diverse applications.

OTP system with third party trusted authority as a mediator

One Time Password is one of the preferable security techniques to do online transaction. If the security level is compared, it shows the need of improvement in its transaction methods and medium. In this paper, two authorities are considered viz. bank domain itself and third party as a trusted authority. Third party authority will have its own secrete key based on its own considered attributes. This key will be combined with user attribute key to form encrypted key. This key will be stored in temp database till session time is available. Here the two new concepts are added as to use third party secrete key and storing this key into temp database for predefined session time only. After these stages only main database can be accessed. It will increase the security level to make secure online transaction.

모바일 OTP의 패스워드 Seed 확장을 위한 지문 중첩 기법

지문은 바이오매트릭스를 이용한 대표적인 신분인증 방법이다. 패스워드 방법에 비하여 도용이나 분실의 위험성이 적은 특징이 있다. 이러한 특징으로 OTP 생성에 지문을 이용한 시도를 하게 되었다. 본 논문은 개발된 OTP 시스템의 프로토타입을 소개하며, 지문을 이용한 OTP 시스템은 와상형 지문의 특징점이 적게 추출된다는 단점을 극복하는 방법을 제안한다. 적은 특징점은 OTP 세션을 위한 많은 암호화 키를 생성하지 못한다. 제안된 방법은 간단하게 동일한 지문을 겹침으로써, 편의를 갖는 중첩된 지문의 많은 특징점이 추가된다. 이로 인하여, 지문을 이용한 OTP의 보안성과 패스워드 추측에 대한 임의성이 강화된다. The fingerprint is the identity authentication method which is representative uses biometrics. Compared with password methods there is a feature where the dangerousness of embezzling or lossing is few. With like these features using the fingerprint in OTP creations. In this paper, we introduce the developed prototype of OTP system using fingerprint. And the overcome method of OTP system's demerit using fingerprint which extracts few minutiae points into a whole fingerprint image is proposed. A few minutiae points wasn't generated many encryption key for OTP session. The proposed method is overlaid the same fingerprint simply and added many minutiae points as biased overlaid fingerprints. Hence the security of OTP using fingerprint and the randomness over password-guessing are strengthened.
